Taxonomic Decision for Synonymy

 

Introduction

Dworakowska (1992) reviewed the genus Empoascanara and recognised 8 "clusters" of species within the subgenus Empoascanara based on the structures of the male genitalia. She allocated the two described Australian species to different groups, E. peregrina Dworakowska to the prima group and E. australensis Dworakowska to the limbata group. A publication describing the 28 undescribed Australian species is in preparation and an analysis of their placement within these groups may reveal some evolutionary trends within the subgenus. The distribution given here includes the undescribed species.

Diagnosis

Vertex of head in length more than half the breadth between eyes, subconically produced anteriorly; face elongate, prominently obliquely narrowed to clypeus, its greatest breadth between eyes more than half its length; pronotum longer than either vertex of head or scutellum, anterior margin moderately convex between eyes, posterior margin truncate; scutellum subtriangular; tegmina more than three times as long as broad, three long apical cells and a somewhat large and prominent subbasal costal cell; posterior tibiae with long, dense spinules (Distant 1918).

Vertex rounded, especially in male, or slightly produced in the middle, always longer than half length of pronotum. Head with eyes equally broad as pronotum. Transition vertex to face rounded. Face quite broad in lower part, lateral frontal sutures strongly convergent (incised) in the middle of their length. Forewing with claval veins hardly visible and 4th apical cell well separated. Hindwing rounded at apex, without submarginal vein there. Male genitalia: pygophore lobe rather short. Pygophore appendage variously shaped but its base broadened and attached to a large area on inner surface of the lobe. In some cases there is a lower pygophore process and in some species there is a distinct additional lobe at hind lower angle. Subgenital plate quite broad apically, pigmented or light. The basal group contains several peg-like setae usually situated on a protruding lobe and this way better distinguishable from other marginal microsetae, becoming smaller and thinner apicad. Marginal plica very well developed and often provided with well pigmented serrated protrusion. Paramere with variously shaped apical part and narrowing lower part. Connective with very well developed central lobe. Penis attached to upper margin of manubrium (Dworakowska 1978).
